Here are 2 vintage Collectors’ Workshop items when they were located in McAllen Texas. Both items are single owner, like new condition (work perfectly), include original boxes, and the price includes USPS priority shipping. - Vienna Frame This effect is based on an old Conradi effect. It is the mechanical visible card restoration version and not the later electronic version. I think this looks much better than the Richard Himber version. My price is $290.00.- Slates Of Solomon. I believe this is based on the rare Milson Worth Satyr’s Slate. The size is 3” x 4” (same size as the Satyr‘s Slate). Briefly, 2 cards are chosen and they appearing in writing on 2 previously shown blank slates. The effect is self-contained (no flaps moving from slate to slate). This is very deceptive with the writing looking like white chalk. If you don’t know the working, it is very difficult to find the inside slate mechanism. My price is $175.00.USA sale only, If interested (photo, questions, etc.) send email to rtysl@wideopenwest.com. Bob Tysl1837 Syracuse Ave.Naperville, Illinois 60565Phone: 630-420-2139
